Stress proteins HSP90 and Gp96 in graft-versus-host disease : pathophysiological, diagnostic and therapeutic implication

2015

Allogeneic hematopoietic cell transplantation is a treatment for certain disorders including hematologic malignancies. Graft-versus-host-disease (GvHD) is a major, life-threatening complication. It is due to the recognition of recipient antigens by donor T cells, which activate and damage tissues. Intestinal barrier alteration plays a critical role in GvHD. Heat shock proteins (HSP)90 include five members, three cytosolic members named HSP90, and one member localized in endoplasmic reticulum (ER) called Gp96 and able to gain extracellular level in case of stress. We show in our thesis that 17AAG, a HSP90 inhibitor, reduces GvHD mortality in a mouse model. This effect is associated with an i…
